To all whom it may concern:

Be it known that 1, ROBERT A. CHRissI-N- one, a citizen of the United States, residing at Stockport, in the county of Van Buren and State of Iowa, have invented certaln new and useful Improvements in Silo- Block Formers; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make anduse the same.

This invention relates to an attachment for clay mills used for forming building blocks, and the primary object of the invention is to provide a table having a curved or arcuate top for receiving the column of clay upon egress from the clay mill, for shaping the block to assume anarc of a circle, so as to provide blocks for use in building circular structures.

Another object of this invention is to slidably mount the table having the arcuate top, and to associate therewith a cutter for cutting the column of clay into blocks of the proper length, and to provide means operable by the movement of the table for automatically operating said cutter.

With the foregoing and other objects in view this invention consists in such novel features of construction, "combination and arrangement of parts as will be hereinafter more fully described, illustrated-in the accompanying drawings and claimed.

In describing the invention in detail reference will be had to the accompanying drawings wherein like characters designate like or corresponding parts throughout the several views, and in which Figure 1 is a side elevation of the improved silo block former, showing'the same used in connection with a rotary clay mill, Fig. 2 is a longitudinal section through the table, Fig. 3 is a cross section through the table, and, Fig. 1 is a detail perspective view of the cutter.

Referring more particularly to the drawings, 1 designates a clay mill of-the rotary type, but it is to be understood, that this invention may be applied-to any similar type of clay mill to that shown, which is used for forming building blocks. The clay mill 1 has an egress spout 2 formed upon the outlet end of the same, to feed a column of clay outwardly upon the receiving table 3. The receiving table 3 has axles 4 and 5 secured to the under surface of its sides 6, a short distance inwardly from its front and rear ends, upon which axles are mounted flanged wheels 7. The flanged wheels 7 ride upon theupper edge of the side plates 9 and 10 of the table construction 11. The table 3 has its upper surface 12 curving upwardly from its forward end, and forming an arc of a circle, as is'clearly shown in Figs. 1 and 20f the drawings. An end gate 13 is pivotally connected to the sides 6 ofthe table 3 at-their rear ends, and at the rear end ofthe arcuate top 12, the purpose ofwhich'will be hereinafter more fully described. The table 11 has a rack bar 14: supported by means of brackets 15, positioned between the facing surfaces of the sides 9 and 10, which rack bar extends longitudinally of the table 11. The sides 6 of the movable table 3 have journaled therein and extending transversely across the table 3, a shaft 16, which has a gear 17 mounted thereupon, intermediate of its ends. The peripheral teeth 18 of the gear 17 mesh with the rack teeth formed 'uponthe rack bar 14:, for rotating the shaft 16 upon the move ment of thetable 3. The gear 17 is loosely mounted upon the shaft 16, and it has pawls 19 and 20 secured to its opposite sides, which are provided for receiving shoulders formed upon collars 21 and 22 respectively, for rotating the shaft synchronously with the rotation ofjthe gear.

'The shaft-16 has disks 23 and 24: mounted upon' its outer end, to which disks are, eccentrically, connected arms 25 and 26 respectively. The arms 25 and 26 are in turn connected to collars 27 and 28. The collars 27 and 28 are slidably mounted on upstanding rods 29'and 30, which are carried by and secured to the sides 6 of the table 3. The collars 27 and 28 have arms 31 formed thereupon, and extending rearwardly therefrom toward the gate 13. A cutter construction 32 is pivotally connected to the arms 31 and it embodies a frame 33, which has angularly disposed ends 34. The ends34 have pins 35 and 36 adjustably connected thereto, to the inner ends of which pins is connected a cutting wire or blade 37. By the adjustment of the pins 35 and 36 the tightness of the cutter blade 37 may be regulated. The pins 35 and 36 extend through the arms 31, and through the upper ends of the eccentric arms 25 and 26. The top 12 is provided of the spout 2, the same passes upon the arcuate top 12 of the table 3. The clay being soft, will curve to conform to the curvature of the top 12, and the forcing action of the column of clay egressing from the spout 2, will force the column upwardly along the upper surface of the top 12, until the end of the column of clay strikes the end gate 13,

which is held in a substantially vertical position by the operator of the device. lVhen the end of the column of clay strikes the end gate 13, further force of the egressing clay will move the table 3 longitudinally upon the table 11. The longitudinal movement of the table 3 will, through the meshing engagement of the gear 17 and the rack 14, rotate the shaft 16, which will in turn rotate the disks 23 and 2 1, and move the cutting construction 82 downwardly, when this construction is positioned at the upper ends of the rods 29 and 30, forcing the cutting blade or wire 37 downwardly through the column of clay, which will cut a block of the proper length from the end of the column of clay. After the block has been properly cut, the end gate 13 is moved to a substantially horizontal position and the block is removed, after which the end gate is again moved to substantially a vertical position and the table 3 is forced forwardly, by man ual power, toward the clay mill 1. The movement of the table 8 toward the mill 1 will force the column of clay upwardly nntil it engages the end gate. During the movement of the table toward the mill, the pawls 19 and 20 will be out of engagement with the shoulders formed upon the collars 21 and 22 and permit the gears 17 to rotate freely upon the shaft 16. When the table reaches its forward position, as is shown in Fig. 1, the column of clay egressing from the spout 2 will again pass upwardly over the arcuate surface 12, and out another block from the column in a manner first described.

From the foregoing description taken in connection with the accompanying drawings the advantages of construction and of the method of operation of the improved block former will be readily apparent to those skilled in the art to which this invention ap pertains and, while in the foregoing description, the principle of the operation of this invention has been described together with various features of construction, it is to be understood that certain minor features of construction, combination and arrangement of parts may be altered to suit practical conditions provided such alterations are comprehended within the scope of what is claimed.
